I need some help with displacement and vectors!!

The displacement vectors A and B shown both have magnitudes of 3 m. The direction of vector A is theta=30 degrees. Find graphically:
(a) A + B
(b) A - B
(c) B - A
(d) A-2B

Report all angles counterclockwise from the positive x-axis.

so B is pointing directly north? and has an angle of 90 degrees?

anonymous · Answer

yep!

jim_thompson5910 · Answer

one way is through the parallelogram method

use the two vectors A and B to construct a parallelogram like so
